To see how this works, start with what happens at the end of a working day

when all the users leave the building. User A happens to leave first, and sets

Partition A from the keypad in Office A. The control unit completes setting

Partition A when the user closes zone 2. A few moments later, users B and C

set their partitions. The control unit completes setting Partitions B and C when

the users close zones 3 and 4 respectively. Finally, user D sets Partition D

from the keypad in Office D. When the user closes zone 5, the control unit

completes setting Partition D. However, the control unit maintains the exit

tone because no one has opened and closed zone 1. When the user leaves

the building and finally closes zone 1, the control unit also sets the common

area.

In the morning, the users return to their offices at different times. The first user

to return is user B. As user B opens the door from the street into the lobby,

the control unit starts the entry timer. User B then opens zone 3 and unsets

Partition B. The control unit stops the entry tone, unsets Partition B and the

common area, and leaves Partitions A, C and D set. User C is the next to

arrive. When user C opens zone 1 the control unit does nothing since the

common area is already unset. The control unit starts the entry timer when

user C opens zone 4. User C unsets Partition C and the control unit stops the

entry timer, but leaves Partitions A and D set. As the morning goes on, users

A and D arrive and unset their partitions in the same way.

Exit Methods

Example 1 uses Final Exit zones on the doors to complete setting of the

system. You can also use Timed Exit zones on zones 2, 3, 4 and 5, with zone

1 as a Normal Alarm zone. In this case, the system sets the common area

after the Exit Time for the last user to leave expires. However, you must make

the Exit Time long enough to let the last user to leave close the door to their

office, cross the lobby and close the last door before the exit timer expires.

Using Exit Terminate buttons is not recommended with common areas. If

there is a single terminate button, one user can press the button while another

is still crossing the lobby. If, on the other hand, you give each user a separate

button, there is always the problem of a user pressing the wrong button.

Things to Avoid

If you use Final Exit Zones to complete setting of the system when all the

users have left, you must not give any user separate access to the outside

world. To see why, look at Figure 38 which shows two partitions sharing a

common area.
